Abstract
We present a study of nonequilibrium superconductivity in DyBa2Cu3O7−δ using photoinduced activation of mm-wave absorption. We monitor the time evolution of the thin film transmissivity at 5cm−1 subject to pulsed infrared radiation. In addition to a positive bolometric signal we observe a second, faster, decay with a sign opposite to the bolometric signal for T>40K. We attribute this to the unusual properties of quasiparticles residing near the nodes of an unconventional superconductor, resulting in a strong enhancement of the recombination time.
